I need to be able to generate virtual credit card account numbers (ala the service provided by DiscoverCard or CitiCards) via my mobile phone browser. The DiscoverCard and CitiCards web services seem to require either Java or Flash support in a browser, neither of which my phone supports. I've got a V3XX, and can use the built-in browser or Opera Mini. Any services out there that would support this configuration?

What's the best wireless phone service for the NYC area? I'm as fed up with Verizon as the next guy, but my limited experience with an iPhone in Manhattan left me with dropped/missed calls and very intermittent access to maps, etc. (unless already cached). Putting aside fun features that usually work, and imagining your life depended on receiving or making a phone call, which network would you choose?* *Please speak from experience with a carrier and nevermind the silly games they play (e.g., crippling bluetooth, etc.); I simply need a service that doesn't miss or drop calls.

We'd like to build an application that can send text messages to people on various cell services. Think something like how twitter works where they give you their cell number, and then you can send messages to them. We've found an easy way to do it via e-mail if you know the service that the person is on, but I have to think there's a better way to handle this. The problem is I'm not sure what keywords to be searching on to find helpful information. Can you point me towards a breakdown of how to set something like this up or help me figure out what keywords I need to find it myself?

I have a siemens C55 telephone that is simlocked. I've also gotten the unlock code off my provider a while back. The problem is I either didn't receive or have lost the unlock instructions, i.e. what exactly I need to type into the phone along with the unlock code, and whether this should be with the original sim card, a new sim card or no sim card at all loaded. I know I can unlock it without the code if I have a data cable, but I don't have a data cable and they'd probably cost more than the entire phone is worth. Googling is made difficult by the millions of sites offering to unlock phones for low low prices.

I'm sure somebody else who's travelling over Thanksgiving could also benefit from this knowledge. I brought my cell phone with me on my five-day trip to my parents' place, but of course I forgot the charger. The question I ask is: 'tis nobler to leave the phone on continuously and hope the battery pulls through, or is it a better idea to turn the phone off every night and turn it on only at the point in the day when I plan to use it? Does powering off and on drain more battery power than idling / the cell phone equivalent of "sleep"? FWIW, I have a relatively new Nokia 6682, and the battery is currently showing a full charge but I suspect it's lying, as I think it's been at least 24 hours since I charged it (that said, this battery's done five days unplugged before).
